红缘吉丁(鞘翅目:吉丁虫科)触角感器的扫描电镜观察

Observation on antennal sensilla of Buprestis fairmairei Thery (Coleoptera, Buprestidae) with scanning electron microscopy

对红缘吉丁BuprestisfairmaireiThery触角感器的超微结构、类型和分布进行了研究。结果表明,红缘吉丁触角具有3种刺形感器、2种毛形感器、4种锥形感器和1种芽孢感器。触角感器在每节上的数量和分布不同。

Antennal sensilla ultrastructure, type and distribution of the buprestid, Buprestis fairmairei Thery, were studied using scanning electron microscope. The serrate antenna of Buprestis fairmairei consists of the scape, pedicel and 9 flagellomeres. Three types of sensilla chaetica, two types of sensilla trichodea, four types of sensilla basiconic and one type of sensilla gemmiformium were distinguished with the shapes and distribution of sensilla. Quantity and distribution of sensilla are different in each segment of antenna.
